How do I support this Ceiling?

[Jdawg]

Hello everyone. need your help!

How can I support this Ceiling without having pillars everywhere? I'm thinking about using Concrete, or is that going to be to heavy to support?

you will need pillars i have a 3 level building and have 2 pillars on ech level, The reason is with no pillars when you build up high with no pillars the floor will suddenly drop and you will fall through. dont matter what type of block it all needs support, you cantest by building say 3 block high then putting a block off of the top one, you can put 2 or 3 without support but going over this it will colapse

yes, and consider building with rebar and upgraded rebar because it has the most strength.

Yeah I think maybe I built the house to big, gotta make som more pillars then. I wish they would add some kind of support beam tho. Thanks for the help guys! =)

weriod i built a 3 story with reinforced concrete with a garden on top and it held?

+1 for support beam, looks better having a horizontal beam across your roof than an ugly pillar in the middle of your room.

You can usually get away with larger spans if you build with walls instead of pillars. Wood needs a pillar every 4th block for proper support. However, I have been successful at building an 8x16 room if I build 4 walls instead of pillars. If I build on top of that, I can't seem to go any longer than 16 without the upper layer collapsing. As a general rule, I build in 8x8 boxes with wood.

Alternative method:

You can build fairly huge buildings without supports for the roof, beyond the outer walls.

I just built this partially to show what I mean.

The material is Decayed brick (made: 1 dirt + 1 brick - where brick is 9 clay to make).

By doubling up the roof as you build it, you can end up with a very sturdy surface to walk on.

A single layer... As you can see in the pictures, it falls apart while the double was completely safe to walk on.

From "on the wall"

From on the floor - the inner open area is 18 across and, as you can see - *NO* supports and far longer span than you can make without support in all directions from the center (which I walked across easily).

That single-brick edge - the missing bricks... I tested walking over a single-depth (to make sure) and they fell out but *NOT* the double thickness.

I think that's a bit bigger than the area you're trying to cover (and yes, it's 3 bricks from the floor to the ceiling so the walls aren't short inside - just deep to the back wall).

If you are going to continue using Brick Paver for the ceiling, it will hold well with the columns that you have. I assume the columns are about 4 blocks away from each other and the walls.

Do not trust the double layered floor/roof or the "glue effect" work around if you are planning on making a tall building.

The pictures I posted are using decayed brick (make bricks, 1 brick + 1 dirt = 2 decayed bricks) but paver works the same way with respect to support.

I expanded the building a bit more but I am wondering what you mean by "making a tall building".

Here's the building fleshed out more - only 3 floors and the roof but... 2nd floor is 5 bricks tall, 3rd floor is 6 bricks tall (5 windows tall + 1 up from floor). The final ceiling is totally unsupported with only a ladder on a 20x20 building.

Total effect, from the floor at ground floor, the building is 20 meters tall the way it's shown and I could add another floor to it just as reliably but it's time consuming to build them to show this stuff.

It's understanding how the physics works in the game to build such things is all (and with over 500 hours played -AND- a *LOT* of testing, I do have a fairly indepth understanding on how to build such things.

The down side to it is that each floor takes 2 times the materials to build them but I could build 30x30 buildings if that were my goal. I don't build ultra tall buldings but this would work to max height.

That "double thick" ceilings is rather reliable and you can mine under the building without worrying about floor spots falling out.


Here are a couple shots:

Oh and the only reason I have columns every 2 windows wide is you can no longer make big glass walls or I'd have done that instead.

You used to (back around alpha 6.x) be able to make huge glass ceilings and/or walls but you can't do that anymore - it must touch a block on some side now.

That building looks good and the design will hold itself very well. You don't even need double floor/roof with that design.

When I mentioned tall, I meant around 50 blocks high or skyscraper tall that's almost if not reaching the sky limit.

Double floor/ceiling can fool you of thinking it can hold a lot of mass because it's not falling apart.

If you want to test it, you can double the roof on your building and then build a 15 block column near the very center since you don't have a column underneath, then try adding blocks horizontally at the tip. You will notice that the blocks no longer sticks.
